    Structure and mechanism of a phage-encoded SAM lyase revises catalytic function of enzyme family

    Xiaohu Guo et al.
    The first structure of a bacteriophage-encoded S-adenosyl methionine degrading enzyme was solved and demonstrated to catalyze a unimolecular lyase reaction occurring at the domain interface of a trimeric structure.

    Mechanisms of opening and closing of the bacterial replicative helicase

    Jillian Chase et al.
    Analysis of the Escherichia coli DnaB helicase•bacteriophage λ helicase loader (λP) complex provides insights into helicase opening, delivery to the origin and ssDNA entry, and closing in preparation for translocation.

    The structure of the COPII transport-vesicle coat assembled on membranes

    Giulia Zanetti et al.
    A structure of the complete, membrane bound, COPII coat solved by sub-tomogram averaging reveals the arrangement of all protein subunits on the membrane and suggests a mechanism for coating heterogeneously-shaped carriers.

    Competing scaffolding proteins determine capsid size during mobilization of Staphylococcus aureus pathogenicity islands

    Altaira D Dearborn et al.
    Cryo-electron microscopy and genetics show how Staphylococcus aureus pathogenicity island 1 hijacks the assembly pathway of a helper phage for its own propagation.

    An integrin/MFG-E8 shuttle loads HIV-1 viral-like particles onto follicular dendritic cells in mouse lymph node

    Chung Park, John H Kehrl
    Intravital imaging with HIV-1 viral-like particle in mouse model reveals a mechanism for HIV-1 uptake by subcapsular sinus macrophages that facilitates HIV-1 spreading tofollicular dendritic and B cells.

    TGF-β reduces DNA ds-break repair mechanisms to heighten genetic diversity and adaptability of CD44+/CD24− cancer cells

    Debjani Pal et al.
    Phenotypic diversity and cell state transition (i.e., acquisition of a CD44+/CD24- cell state or exposure to TGF-beta) can spur intra-tumor genetic heterogeneity and contribute to acquired resistance.

    Firefly genomes illuminate parallel origins of bioluminescence in beetles

    Timothy R Fallon et al.
    The first genomic view of beetle luciferase evolution indicates evolutionary independence of luciferase between fireflies and click-beetles, and provide valuable datasets which will accelerate the discovery of new biotechnological tools.

    RNA Polymerase II cluster dynamics predict mRNA output in living cells

    Won-Ki Cho et al.
    Quantitative super resolution imaging, in live mammalian cells, reveals a direct relationship between protein clustering dynamics and the number of mRNA transcribed at an endogenous gene locus.

    Antibacterial gene transfer across the tree of life

    Jason A Metcalf et al.
    Parallel horizontal gene transfer has spread a bacteriolytic gene family to all domains of life, and has bestowed a niche-transcending adaptation in recipients that must deploy antibacterial molecules to survive in a bacterial world.

    All-atom molecular dynamics of the HBV capsid reveals insights into biological function and cryo-EM resolution limits

    Jodi A Hadden et al.
    All-atom molecular dynamics of the HBV capsid supports a role for structural asymmetry in biological function, reveals the potential for triangular pores to mediate cellular signaling, and indicates that capsid flexibility may limit resolution attainable by cryo-EM.
